Tremendous Transformation
Once during your turn (before your attack), if Ditto is your Active Pokémon, you may flip a coin. If heads, choose any Pokémon in play. From now on treat Ditto as if it were the same card as that Pokémon, including Hit Points, Weakness, and so on, except Ditto can't evolve or devolve, always can use this Pokémon Power, and you may treat any Energy attached to Ditto as Energy of any type. If tails; if Ditto is Benched; if Ditto becomes Asleep, Confused, or Paralyzed; or if the Pokémon you chose leaves play, treat this card as Ditto again. This power can't be used if Ditto is Asleep, Confused, or Paralyzed.
